| DATA_SET_DESCRIPTION |
Data set Overview : Rosetta was at distances between 320 and 46 km from the comet during this time. ROSINA was permanently analysing the coma of the comet with all three sensors, except during wheel offloadings, when the mass spectrometers DFMS and RTOF were in standby and during orbit control manoeuvers, when all sensors were off. Explanation on the data generation of the ROSINA sensors can be found in the OPERATION_LOGBOOK.ASC Parameters : DFMS and RTOF data contain neutral gas data as well as ion data. The data are raw, uncalibrated data. COPS data contains nude gauge pressure values of the combined spacecraft and cometary signal. For calibrated data we refer the user to the level 3 data. Calibration : COPS data are calibrated. However, the calibration factor has been determined for nitrogen gas, and may not be appropriate for the coma composition. To properly calibrate the COPS densities and process the L4 PDS data, the molecular ratios from the DFMS CODMAC L3 PDS have to be taken into account to correct the COPS L2 PDS. Processing : The processing of the COPS CODMAC L2 to L4 PDS derived data is detailed in the COPS_PDS_L2_TO_L4.PDF document. Software : No software will be provided. Media/Format : The standard distribution format for the data is an electronic volume. Coordinate System : The geometry items SC_SUN_POSITION_VECTOR, SC_TARGET_POSITION_VECTOR and SC_TARGET_VELOCITY_VECTOR provided in the label of the data product are relative to the Earth Mean Equator and Equinox reference frame of J2000. SUB_SPACECRAFT_LATITUDE, SUB_SPACECRAFT_LONGITUDE are given in the Cheops reference frame. The SPACECRAFT_ALTITUDE gives the distance to the spacecraft from the target center of mass. These parameters are computed at time t:START_TIME. Distances are given in km, angles in degrees.
